Frequently asked questions

Does this work for scanned pages?

Yes. The tool renders each page as an image and looks for non-white pixels to determine the content boundary.

Are pages converted to images?

Yes, because the tool uses pixel analysis. Text stays visible but loses selectability.

Are my files uploaded?

No. Everything happens in your own browser. Your file never leaves your device and is not stored anywhere.

Is it free?

Yes, completely free and without watermark, ads or account.
